director: Don't send USERs in handshake that were already sent between handshake If the user was refreshed since the handshake was started, it means that the same user was already sent to the other side (added to the stream immediately after it was received/handled). There's no need to send it again. This fixes a potentally infinite handshake when users are rapidly changing and the handshake iterator never sees the end of the list. (Each refreshed user is moved to the end of the list, so handshaking can keep sending the same user over and over again.)

global: use i_rand_limit() and i_rand_minmax() when possible

global: Replace rand with i_rand

director: Make sure users gets expired even on an idle director Normally expiring gets done while looking up users, but if nothing is doing that on an idle director the users won't get expired. This can cause confusion in "doveadm director status" output.

global: Use const for all test_functions[] arrays

director: Code cleanup - Reorder includes This is required to enable typedef of user_free_hook

director: Code cleanup - moved username_hash generation to director.h It's not really user_directory specific. This is especially important in the following patches that add per-tag user_directories. It's also not always known which tag the username_hash refers to, so there can't be different tag-specific username_hash generators.

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

director: Moved all user killing state to struct director_kill_context This should make it a bit easier to understand the life time of user killing. It also simplifies code by removing struct director_user_kill_finish_ctx. Finally, this already reduces memory usage with 32bit systems, and would make it possible to reduce also on 64bit systems if timestamp is shrank to 31 bits and weak bit moved after it. I'm not sure if that would be better for performance though. In any case it would provide free space for 4 extra bytes if that were needed in future.

Oops :) Update copyrights to 2013 without breaking all .c files.

Make sure we check all the functions' return values. Minor API changes to simplify this. Checked using a patched clang that adds attribute(warn_unused_result) to all functions. This commit fixes several error handling mistakes.
